The weight-loss industry is blooming. Each passing year, it is fueled by people's constant desire to lose weight.

Also known as the “princess diet,”, the Dukan Diet was invented by French doctor Pierre Dukan, based on a principle that has been on the weight-loss diets scene for more than three decades. But it wasn't until 2000, when the doctor published his book, that the diet became popular. The Dukan diet recommends protein consumption and excludes fats and carbohydrates. It is a high-protein, yet a low-calorie type of diet. There is a list of 100 foods that are allowed, out of which 72 are of animal origins. The diet raised a lot of controversy, because it excludes entire groups of nutrients.

A study on 5,000 patients that followed the Dukan diet shows that 80% of them put the weight back on when they stopped dieting. Pierre Dukan earned a fortune from selling and promoting his book and diet pills, especially after Hollywood celebrities like J Lo claimed it works, but apparently it puts the body under a lot of pressure.
